1. Introduction
The QK-AS08 is a compact, high-performance gyro electronic compass and attitude sensor. It has an
integrated 3-axis magnetometer, 3-axis rate gyro and together with the 3-axis accelerometer uses
advanced stabilization algorithms to deliver precise, reliable heading and vessel attitude including rate of
turn, pitch and roll readings in real time.
With solid state electronic technology and additional software, the AS08 provides better than 0.4° heading
accuracy through ±45° of pitch and roll angle and also better than 0.6° pitch and roll accuracy in static
conditions.
The AS08 has been pre-calibrated for maximum accuracy and
super electromagnetic compatibility.
It can
be used out of the box. Simply connect it with a 12VDC power source and it will immediately start
calculating the heading, pitch and roll data of the boat and outputting this information. You can filter out
this message type if not required (using the Windows configuration tool with AS08).
The AS08 outputs the NMEA 0183 format data via USB and RS422 port. Users can easily connect it to
their computer or NMEA 0183 listeners to share information with navigational software, chart plotters,
autopilots, vessel data recorder, and dedicated instrument displays.

2.1. Dimensions, mounting and location
Figure 1 Dimensions
AS08 is designed to be securely positioned in an indoor environment. The AS08 should be mounted to a
dry, sturdy
,
horizontal surface. The cable can be routed either through the side of the sensor housing, or
through the mounting surface under the sensor.
For best performance, mount the AS08:
•
As
close to the vehicle/boat’s centre of gravity as possible.
•
To accommodate the maximum pitch and roll motions, mount the
sensor as near to horizontal as possible.
•
Avoid mounting the sensor high above the water line because doing so also increases pitch
and roll acceleration
•
AS08 does not require a clear view of the sky.
